The Blue Flag is a world-renowned eco-label certification for beaches, marinas and boats.

It is operated under the auspices of Foundation for Environmental Education (FEE), an international not for profit organization, headquartered in Copenhagen, Denmark.

The programme, initiated in France in 1985, is recognized by the United Nations Education for Scientific and Cultural Organization (UNESCO) as an innovative Education for Sustainable Development (ESD) programme that creates opportunities for local communities, businesses and administration to empower themselves to sustainably manage beach spaces, encourage responsible tourism and contribute towards the conservation of natural resources.

In India, the Blue Flag programme is implemented by the Society for Sustainable Urban Development, as the National Operator.
